Dova Pharmaceuticals Receives Positive Opinion from CHMP for DOPTELET® (avatrombopag) for the Treatment of Thrombocytopenia in Patients with Chronic Liver Disease

Positive Opinion based on positive efficacy and safety data from two Phase 3 clinical trials


DURHAM, N.C., April 29, 2019 (GLOBE NEWSWIRE) -- Dova Pharmaceuticals, Inc. (NASDAQ: DOVA) today announced the Committee for Medicinal Products for Human Use (CHMP) of the European  Medicines Agency (EMA) adopted a positive opinion for the use of DOPTELET® for the treatment of severe thrombocytopenia in adult patients with chronic liver disease (CLD) who are scheduled to undergo an invasive procedure.

“CHMP’s positive opinion for DOPTELET marks another significant achievement for Dova, a key step forward in our efforts to expand the availability of DOPTELET to patients with thrombocytopenia and CLD globally,” said Dr. David Zaccardelli, President and Chief Executive Officer of Dova. “We look forward to continuing to work with the EMA to obtain marketing authorization approval in Q3 2019.”

The submission was supported by safety and efficacy data from two global Phase 3, double-blind, placebo-controlled trials (ADAPT-1 [N=231] and ADAPT-2 [N=204]), conducted in adults with thrombocytopenia (platelet count of less than 50,000/µL) and CLD. DOPTELET was shown to be superior to placebo in increasing the proportion of patients not requiring platelet transfusions or rescue procedures for bleeding up to 7 days following a scheduled procedure in both trials in both the 40 mg (ADAPT-1, 88% vs. 38%, p <0.0001; ADAPT-2, 88% vs. 33%; p<0.0001), and 60 mg (ADAPT-1, 66% vs. 23%, p <0.0001; ADAPT-2, 69% vs. 35%; p=0.0006) treatment groups. DOPTELET was also superior to placebo at the two secondary efficacy endpoints in each trial, the proportion of patients achieving a platelet count equal to or greater than 50,000/µL, and the magnitude of the change in platelet counts from baseline to procedure day.

DOPTELET, a second generation, orally administered thrombopoietin receptor agonist (TPO-RA), was approved by the U.S. Food and Drug Administration (FDA) for the treatment of thrombocytopenia in adult patients with chronic liver disease (CLD) who are scheduled to undergo a procedure in May 2018.

Indications and Important Safety Information
(Based on FDA-Approved Labeling)

INDICATIONS

DOPTELET (avatrombopag) is approved for the treatment of thrombocytopenia in adult patients with chronic liver disease who are scheduled to undergo a procedure.

IMPORTANT SAFETY INFORMATION

WARNINGS AND PRECAUTIONS

DOPTELET is a thrombopoietin (TPO) receptor agonist and TPO receptor agonists have been associated with thrombotic and thromboembolic complications in patients with chronic liver disease. Portal vein thrombosis has been reported in patients with chronic liver disease treated with TPO receptor agonists. In the ADAPT-1 and ADAPT-2 clinical trials, there was 1 treatment-emergent event of portal vein thrombosis in a patient (n=1/430) with chronic liver disease and thrombocytopenia treated with DOPTELET.

Consider the potential increased thrombotic risk when administering DOPTELET to patients with known risk factors for thromboembolism, including genetic prothrombotic conditions (Factor V Leiden, Prothrombin 20210A, Antithrombin deficiency or Protein C or S deficiency). 

DOPTELET should not be administered to patients with chronic liver disease in an attempt to normalize platelet counts.

CONTRAINDICATIONS:

None

ADVERSE REACTIONS

Most common adverse reactions (≥ 3%) are: pyrexia, abdominal pain, nausea, headache, fatigue, and edema peripheral.
